Why the study?
What are the mechanisms and predisposing factors for sudden cardiac death and ventricular arrhythmias associated with antidepressant and antipsychotic drugs?
What are the mechanisms and predisposing factors for sudden cardiac death and ventricular arrhythmias associated with antidepressant and antipsychotic drugs?
This review highlights the mechanisms by which certain antidepressant and antipsychotic drugs predispose patients to life-threatening ventricular arrhythmias and sudden cardiac death.
Warrants ECG monitoring consideration in high-risk patients; extends mechanistic insights but leaves causal confirmation open.
A number of antipsychotic and antidepressant drugs are known to increase the risk of ventricular arrhythmias and sudden cardiac death. Based largely on a concern over QT prolongation and the development of life-threatening arrhythmias, a number of antipsychotic drugs have been temporarily or permanently withdrawn from the market or their use restricted. Some antidepressants and antipsychotics have been linked to QT prolongation and the development of Torsade de pointes arrhythmias, whereas others have been associated with a Brugada syndrome phenotype and the development of polymorphic ventricular arrhythmias. This review examines the mechanisms and predisposing factors underlying the development of cardiac arrhythmias, and sudden cardiac death, associated with antidepressant and antipsychotic drugs in clinical use.
